Communication operation and setting Parameter
6 - 240
●
For FR-E700 SC ENE
– The inverter operation after occurrence of a fault in the Ethernet communication line or an
Ethernet board fault can be selected.
– The operation at a communication error can be selected with Pr. 502 when Pr. 851 "Ethernet signal
loss detection function selection" = "3 (initial value)" or Pr. 852 "Ethernet communication check
time interval" "9999" during Ethernet communication.
– When an Ethernet communication error is detected while Pr. 851 "Ethernet signal loss detection
function selection" = "2 or 3 (initial value)", the alarm (LF) signal is output via an output terminal
of the inverter. For the LF signal, set "98 (positive logic) or 198 (negative logic)" in any of Pr. 190 to
Pr. 192 ("Output terminal function selection") to assign the function to the output terminal.
